                                <h3>题目描述</h3><p><p><span style="font-size: medium">　　在平面直角坐标系中，Wayne需要你完成n次操作，操作只有两种：<br />
　　1.0 x y。表示在坐标系中加入一个以(x, y)为圆心且过原点的圆。<br />
　　2.1 x y。表示询问点(x, y)是否在所有已加入的圆的内部（含圆周），且至少在一个圆内部（含圆周）。<br />
　　为了减少你的工作量，题目保证圆心严格在x轴上方（纵坐标为正），且横坐标非零。<br />
</span></p></p><hr/><h3>输入格式</h3><p><p><font size="4">　　第1行一个整数n。<br />
　　接下来n行，每行第一个数是0或1，分别表示两种操作。<br />
　　接着有两个实数x和y，具体意义见题面。<br />
</font></p></p><hr/><h3>输出格式</h3><p><p><font size="4">　　对于每个询问操作，如果点在所有已加入的圆内（或圆周上），则输出&ldquo;Yes&rdquo;（不含引号）；否则输出&ldquo;No&rdquo;（不含引号）。<br />

0 -3.0000 2.0000
